TB420 is an intelligent two-wire 4-20mA gas sensor module from German manufacturer EC Sense. It adopts high-reliability solid polymer electrochemical gas detection technology and intelligent algorithm design, complying with industry standards for gas safety monitoring.
Technical Parameters:
Detection Principle:Solid polymer electrochemical
Output Signal Interface:Two-wire 4-20mA (convertible to 40-200mV via external resistor)
Operating Voltage:9-24V DC
Current Consumption:3-22mA@24V DC
Power Consumption:<0.6W
Maximum Loop Resistance:<500Ω@24V DC
Protection:Reverse polarity protection
Operating Temperature:-40°C to +55°C
Operating Humidity:15-95%RH (non-condensing)
Pressure Range:Atmospheric pressure ±10%
Storage Temperature:0°C to 20°C
Dimensions (with sensor):45x35x11.9mm

Packaging:ESD BAG (120x150mm)
Functional Features:
Factory Pre-calibration:Gas-calibrated at the factory, with calibration data stored in Flash memory. Users can use it directly or perform secondary calibration via EC Sense's calibration software, or calibrate 4-20mA signals directly.
Sensor Health Monitoring:Outputs sensor performance and lifespan indicators, as well as fault signals. Regularly provides real-time health status (normal operation, failure, maintenance needed, replacement required) with or without the target gas.
High Performance:Fast gas response, stable zero point without drift, strong EMI resistance, long-life gas sensor with anti-poisoning capability.
Environmental Protection:PCB coated with dust-proof and corrosion-resistant layers.
Development Efficiency:Shortens development time for gas monitoring instruments, reduces design costs and risks, accelerates production cycles by eliminating complex gas calibration processes, and improves instrument reliability and accuracy.
Industrial Compatibility:Standard 4-20mA industrial signal mode enables quick integration into monitoring systems, display meters, DCS, PLC, etc.
